backups stop working

I was play backups fine on my ps2.
Then I made A copy of Teen age mutant turtles. I work fine.
The next day I stop playing games. I use a swap chip it wont play back up movies now and I did not need a chip for that

I Trided cleaning it but I did not Work. I know the games are no problem because they work fine on my freids system. COuld the lens have gone out of wack so it would not read the Dvd+r's. and can you repair this.

stop playing backups or all together? if all of them it's defently lens and it's die OR it can be the ps2 itself do you hear a sound of the lens going up or down of the reader moving or the cd spinning if yes it's a ps2 problem... if you dont hear anything it's the lens... see when the lens goes to heaven the spinning proces dont work anymore... the lens try to read then spins 1 inch then stops then you should replace the lens..

Before buying a new laser you can check the calibration of the laser (pots on the bottom of laser) or checking to make sure that the alignment on the disc that holds/spins the disc is horizontally correct. Things to check before spending the cash. It still could very well be your laser especially if you are still running with a ver 1 or 2 ... good luck.
